Auto rotation of adjustable key switch

A key structure comprising:

• an upper key stem;
• a lower key stem;
• a rotatable middle key stem including a magnetized element disposed therein, the rotatable middle key stem coupled between and in axial alignment with the upper and lower key stems,
• wherein the rotatable middle key stem is operable to be longitudinally rotatable between a first and second position,
• wherein the upper and lower keys stems are rotationally fixed;
• a magnetic field generator configured to steer a magnetic field through the magnetized element of the rotatable middle key stem,
• wherein the generated magnetic field, when at a first setting, applies a first magnetic force on the magnetized element causing the middle key stem to rotate to the first position, and
• wherein the generated magnetic field, when at a second setting, applies a second magnetic force on the magnetized element causing the middle key stem to rotate to the second position.

A keyboard comprising:

• one or more processors;
• a plurality of depressible key structures, each key structure comprising:
• an upper key stem;
• a lower key stem;
• a rotatable middle key stem including a magnetized element disposed therein, the rotatable middle key stem coupled between and in axial alignment with the upper and lower key stems, the rotatable middle key stem including a protrusion,
• wherein the rotatable middle key stem is operable to be longitudinally rotatable between a first and second position while the upper and lower keys stems remain longitudinally stationary;
• a biasing element configured adjacent to the middle key stem;
• a U-shaped metal bar with a first end and second end, the first and second ends configured adjacent to and on opposite sides of the middle key stem;
• and
• a coil having a first side and a second side, the coil coupled to the metal bar, the coil, when energized by a power source, operable to generate a magnetic field,
• wherein the generated magnetic field, when at a first setting, magnetically manipulates the magnetized element causing the middle key stem to rotate to the first position where the biasing element interfaces with the protrusion when the key structure is depressed causing a first feedback effect,
• wherein the generated magnetic field, when at a second setting, magnetically manipulates the magnetized element causing the middle key stem to rotate to the second position where the biasing element does not interface with the protrusion when the key structure is depressed causing a second feedback effect, and
• wherein the one or more processors are operable to control an electrical current flowing through each coil of the plurality of depressible key structures including a first current that sets the generated magnetic field to the first setting, and a second current that sets the generated magnetic field to the second setting.
